Crash on 6-week routine restart

One of my Iotawatts became unresponsive after a “six week routine restart”. No data gathering or web access for the duration, but could ping the unit. Rebooted and all is working. Wifi RSSI has gotten worse from before though, now at around -79.

11/08/21 09:16:40 timeSync: Six week routine restart.

** Restart **

SD initialized.
11/11/21 19:27:44z Real Time Clock is running. Unix time 1636658864

It would have been helpful to note the led state. Also, the log from the subsequent successful restart would be of interest.

Here is the balance of the log after the restart. The way I have the units installed it is almost impossible to see the LED status unfortunately.
